  • 192.99.3.127 is number 1, but it will start from the next. # ufw insert 1 deny 114.143.59.202 to any ERROR: Wrong number of arguments

Reset to default

The order of the firewall rules is important. Since you have allowed 80 for all at the beginning, this rule will match for all request and the deny rule that comes later will never be matched.

So, if you need to block something particularly, put it at the beginning and then allow all.

To see your rules with a reference number, use this:

sudo ufw status numbered

Then remove the deny rule first that you have added:

sudo ufw delete rule_number_here

Then add it again at the top: 

sudo ufw insert 1 deny from xx.xx.xx.xx to any

  • Now it is very good. But, I can not continue adding IP. I added an additional post in the body.
